The Wizard of Oz has built two Ozzy spaceships to present to Princess Ozma. But before he can show them to her one of them mysteriously takes off with the Tin Woodman, Jellia Jamb, and the Soldier with the Green Whiskers aboard.

The errant spaceship flies to Stratovania where King Strut learns of Oz and decides it really belongs to him--and he want Jellia to become his wife!

Soar to the Stratosphere with Dorothy, the Scarecrow, and the Wizard of Oz himself as they attempt to find the missing Ozoplane and save Oz and Jellia Jamb from the clutches of King Strut in Ruth Plumly Thompson's Ozoplaning with the Wizard of Oz.
